Yes. And no. Well, let me explain.
The past four playsets have had figures, so they have all required the full sculpting fees of a figure. The Labs was done by hand, but the EM stage was drawn 100% by me and sculpted overseas. The Kitchen shell, doors, appliances and such and some of the kitchen accessory pieces were drawn by me, some of the organic stuff was hand sculpted. The Swine Trek was all hand sculpted but could have been drawn if I had had the time.
All you gotta do to make it happen, is basically draw every part separately in a technical drawing of all the stage elements, do some 3-D sketches and show how it all fits together and any stage props could be drawn and then maybe replicated or hand sculpted and then sent overseas for replication.
